Abstract The Surface Mining Control and Reclamation Act (SMCRA) of 1977 requires that mine operators reclaim mined land to achieve productivity levels equal to or greater than premined conditions. Presently, the standard for evaluating reforestation success is based solely on tree-seedling survival. This method is an estimator of stand density and not an indication of site productivity. There exists a need to evaluate mine soils based on their capability of growing merchantable timber. This model would aid the reclamation process by providing a means for assessing mine soils based on their quality and productivity.
